In this embodiment, the working principle of the manual self-loading unloading device is briefly described as follows: Initially (when the display screen is connected to the mounting frame), the ejection lever 6 abuts on the concave curved surfaces 423 of the two cams 42 and is electrically operated. The driving member 3 drives the rotation shaft 9 to rotate, which will drive the cam 42 sleeved on the locking section 92 of the rotation shaft 9 (in this process, the rotation handle 7 and the cam 42 connected to the rotation handle 7 do not rotate). The second semi-circular section resists the push-out lever 6 so that the push-out lever 6 moves away from the transmission component 4, so that the wedge 61 on the push-out lever 6 bears against the roller on the mounting frame to separate the display screen from the mounting frame. Body purpose. Similarly, when the user operates the rotary handle 7, similar to the above process, the rotation of the rotary handle 7 does not cause the rotation of the rotating shaft 9. The rotating shaft 9 only provides the installation position for the cam 42 connected to the rotating handle 7. .
